+Dan O'Connell Quote wikipedia on Coka: "Coca is any of the four cultivated plants in the family Erythroxylaceae, native to Southwest America. [...] The alkaloid content of coca leaves is low, between 0.25% and 0.77%.[3] This means that chewing the leaves or drinking coca tea does not produce the high (euphoria, megalomania, depression) people experience with cocaine. Coca leaf extract had been used in Coca-Cola products since 1885, with cocaine being completely eliminated from the products in or around 1929.[4][5] Extraction of cocaine from coca requires several solvents and a chemical process known as an acid/base extraction, which can fairly easily extract the alkaloids from the plant."

Do you think, for confirmation, it might be worth trying a non-group 1 base, since sodium and lithium are both group 1?

@IamGrimalkin

@Quintinohthree

8 жыл бұрын

+IamGrimalkin Alkali here refers to the solution they make when dissolved in water. All basic solutions are alkaline. Alkali metals in aqueous solution have barely any effect on any reaction, though if any effect was induced this would be periodic. Seeing as sodium and lithium appear to react similarly I'd say there's nothing special about the alkali metals here.

@IamGrimalkin

8 жыл бұрын

Quintinohthree Yes, presumably, and that seems more likely than not. But you won't know for sure unless you use a non-group 1 base and see whether you get the same effect.

@Quintinohthree

8 жыл бұрын

+IamGrimalkin True, but not every experiment is worthwhile. If you have reasonable suspission that another similar reagent might react differently, you can make it into a hypothesis and test it. In this case though I think previous observation and established knowledge suggest changing alkali metal hydroxides for calcum hydroxide or some other similar chemical would have little difference, except perhaps because calcium interacts more strongly you'd get more reactions occurring, like the precipitation of calcium carbonate, which might obscure the reactions you were studying.

One of the most interesting science video I saw on the internet. An experiment, an explanation of the reactions. A counter-experiment to test an hypothesis and the building of a theory that will lead to other experiments to confirm it. That's the full path of scientific work.

Great video professor, this was really quite interesting.

It is really amazing and inspiring to see than despite of years of experience with chemistry, you still love it to the extent you literally like to play with it in a very casual way! Really cool experiment! :D

I love these videos, really interesting experiments with simple items.

It's quite amazing what you can discover and learn from something that started out as a mere joke. I hope that this is investigated further and you guys discover whether or not you actually did create an indicator, that'd be pretty cool!

Now _this_ is the chemistry I came here for. Fantastically interesting video!

That was quite an interesting look into how chemists might go about experimenting on unknown solutions. Something about this video struck me as, "Ah, so this is where the fun in chemistry is!" Making a hypothesis, testing via experiment, formulating conclusions... The scientific method felt so restrictive and contrived when I learned it in high school, but seeing it applied here in such a casual and natural manner really displays its power and utility in a way I have not seen before.

That was really cool and interesting. Glad I took chemistry in high school so I could understand the technical stuff.

We used to do some crosslinking experiments with mono, and di-sacharides (sacharose, galactose... etc) using different bases (NaOH, NH3 and even benzyltrimethylammoniumhydroxide) and an epoxide as crosslinker. Even in the control test without the epoxide crosslinker the brown color was formed. the more alkaline the solution the more rapid the color was formed. it smelled somewhat like syrup/caramel. To quenche the reaction we added acid, and also here the solution turned colorless overtime. If you store the unquenched solution in the fridge for about a week its colorless again. Q-TOF results showed it was a polysacharide of the monosacharide added to the solution. mostly formed by bonds formed at the secundaire alcohol.

Fascinating. I'll have to experiment with this in the lab next time I go to the office. Thanks!

Great video! Thanks for uploading
